batch-file - 批量解析字符串输出

Question

我通过在批处理程序中调用 avp.com 获得了来自扫描的卡巴斯基输出。我在一个名为 RES 的变量中有这个输出，这个变量的内容是:

我需要解析这个字符串才能得到 检测到的总数 值，在上面的例子中是 0 .我试过 为 批处理语句，但没有得到预期的结果。
注意:用@mbroshi的anwser编辑

set KAVDir="C:\Program Files (x86)\Kaspersky Lab\Kaspersky Endpoint Security 10 for Windows\avp.com"
for /f "tokens=3 delims= " %%i in ('%KAVDir% /i0 %1 ^| FINDSTR "Total detected"') 
do 
( 
SET RES=%%i 
ECHO %RES% 
)

avp.com 程序执行的输出文本是:

Answer 1

@ECHO OFF
SETLOCAL
set KAVDir="C:\Program Files (x86)\Kaspersky Lab\Kaspersky Endpoint Security 10 for Windows\avp.com"
FOR /f "eol=#tokens=2delims=:" %%a IN ('%KAVDir% /i0 %1 ^|find "Total detected"') DO SET /a totdet=%%a
ECHO Total detected is %totdet%
GOTO :EOF

请注意 findstr "Total detected"将找到任何包含“总计”的行 或 “检测到”，因此使用 FIND (也可以用 findstr /c:"Total detected" 完成)
